Personally, I feel that without the auto import, the feature would be totally useless.

The issue I have with the fn() prefix is that it looks "weird" in case you are chaining multiples. And it looks like a function call, but it isn't one. fn($x) => fn($y) => fn($z) How does hack solve this? Do they have backtracking in their parser?
